To use the service it is necessary to log in with you valid institution credentials to AcademicCloud.
You can use the service very easily via the web interface
You can download the desktop client for your operating system from owncloud.org and install it. For instructions on how to install and work with the desktop client, see the online manual for the client. Apps for mobile devices (Android and iOS) are also available on owncloud.org.
Open the client and enter the following URL as the ownCloud server: https://owncloud.gwdg.de/
After successful login you are at the “Home” level of your account and get the list of your folders as well as the menu on the left side.
Creating folders, uploading files
Deleting files, folders, restoring content
To transfer large files or a large number of files it is recommended to use the client software. Additionally the client can watch your files for changes and upload them to the service in the background or receive changes. This way your files are always up-to-date on the service and your connected devices running the client.
Client downloads and installation information is available for Windows, OS X, Linux and mobile plattforms.
The following describes using the Windows, OS X and Linux client.
After installation a wizard will help you to complete the setup:
Your owncloud folder is now getting saved to your device and will be updated as long as the client is running.
Stop synchronization and delete folder
Options to share content or change and remove access to it are integrated into the file manager: Finder on Mac OS X, Explorer on Windows, Caja, Nautilus and Nemo on Linux (Linux users must install the matching plugin). Right-click the file or folder you want to share and click “Share with ownCloud”. The “Share with ownCloud” dialog has the same options as the web interface. You can see who you have shared this item with, modify their permissions, delete the share, share via a link and set an expiry date or a password for the link.
Content can be shared with specific users or anonymous access can be granted. Invite users to folders
Share contents through links
Note that disabled or expired links are not deleted, only access to the shared content via link is removed.
Q: What does the addition “federated” behind the email address mean when sharing with other users?
OwnCloud uses the "Open Cloud Mesh" protocol to enable cross-instance sharing, e.g. as a user of Sync & Share Service you can share a file with a user of the https://www.sciebo.de/Sciebo cloud without having to create an account on sciebo.de To create such a share you need the “Federated Cloud ID” of the recipient. You can find your own Federated Cloud ID in the settings of your account.
If you enter an e-mail address to share files with other ownCloud users, ownCloud will automatically search for accounts registered at this address. When a match is found, two options are displayed: the found account, for example “email@example.com”, and “firstname.lastname@example.org (federated)” as federated cloud ID.
Note: If only the “federated” variant appears after entering the e-mail address, no matching ownCloud account can be found. Usually the reason for this is that the user has not yet logged in to ownCloud, as the account is not created until the first successful login.
Note: In case of federated sharing, the recipient of the share cannot use any integrated services of Sync & Share, e.g. Web Office, as an account in Sync & Share is required to access Web Office. Alternatively a share via public link is possible.
Q: Can I use the Sync & Share Service for backup?
The Sync & Share Service is no replacement for a regular backup!
The Sync & Share Service is a sync and share service, it
Q: How is my data encrypted in the OwnCloud?
Although ownCloud offers this feature, server-side encryption gives a false sense of security because it can always be defeated by reading the key, whether by the admin or a compromised system.
Therefore, if customers want to store critical data (up to data protection level C), they should first encrypt it themselves on the client side (before uploading). There are various tools for this purpose: Cryptomator, Boxcryptor, encfs to name just a few examples.
Q: Individual files are not downloaded to my Windows PC, but I can see them in the cloud. What could be the reason?
Check if the file name in the cloud ends with a space or contains any of the following characters:
Windows cannot create file and directory names with a space at the end and one (or more) of these characters, so the ownCloud client cannot sync them. Also Unicode characters may cause this problem. This problem can occur when working with Mac OS or Linux operating system users, as these devices can create such files.
To fix the problem, rename the file(s) in the Sync & Share web interface, the client will download them at the next sync.
